Title: Magnetic tape device
Inventor: HOSOKAWA SHIGEFUMI
IPC: G11B5/48
Filed: 1984-01-28
Abstract: PURPOSE:To displace a recording head and a reproducing head in the tape running direction so that the spacing loss is minimum or not only the spacing loss but also the azimuth loss is minimum. CONSTITUTION:Two displacing members for the reproducing head, for example, piezoelectric elements 14 and 15 are attached between a side wall 1a of a substrate 1 and a flat spring 12, and their front end parts press the flat spring 12 in the tape running direction. Consequently, when piezoelectric elements 14 and 15 are driven by equal voltages, the shaking motion of a reproducing head 2 in the tape running direction is possible. The same may be said of a recording head 3. The direction and the magnitude of this shaking motion are controlled properly to set the position of a reproducing core gap 5 or a recording core gap 7 to a minimum spacing position. When piezoelectric elements 14 and 15 are driven by different voltages, the reproducing head 2 performs the twisting motion. Consequently, the azimuth loss is made minimum.

Title: Movable stage device
Inventor: SATO FUMIAKI
IPC: G03F7/20
Filed: 1990-01-24
Abstract: PURPOSE:To give strength to a base sufficiently even in case of the generation of the moment by the weight of a stage and to prevent the deformation of the base, by arranging a movable part interposed with the gap of 1st and 2nd base members and capable of a relative movement with non-contact to the 1st and 2nd base members. CONSTITUTION:A movable part 16 supported with non-contact in the gap of 1st and 2nd base members 11, 13 is moved in this gap. The base easily becomes high at its stifness because of its being of a plane body different from a colum nar guide rail. So, the deformation is not caused actually even in case of the weight of the movable part 16 being given. Moreover the moment generation by the weight of the movable part 16 is difficult to be caused, even in case of a vertical movable stage, because of the two bases 11, 13 being of the struc ture of interposing the movable part 16, a sufficient strength is given to the bases 11, 13 without causing the movable part 16 weight increase if any and the deformations of the bases 11, 13 are prevented.

Abstract: PURPOSE:To have a decorative sound-absorbing plate with excellent design by scratching the facial layer of a mineral fiber plate having a certain specific gravity with a brush roll implanted tightly with elastic needles of specified wire dia., and allowing scratch grooves to meander and intersect through the action of resistance difference in excavation due to density difference over the plate. CONSTITUTION:The facial layer of a mineral fiber plate 5 having a mean specific gravity of 0.3-0.4 is scratched by a brush roll 3 implanted tightly with elastic needles 2a of no more than 1.0mm in wire dia. while the tip of each needle 2a bitten into the plate 5 and rotation is held. Therein the spacing of scratch grooves shall be under 5mm, and a number of holes of 0.5mm or more in dia. be provided so as to allow easy biting-in of the tip of the needle 2a into the surface of the plate 5. The difference in the excavation resistance due to density difference in the plate 5 causes meandering and intersection of the scratch grooves 4, which produces irregular grooves having high sound absorbing performance. Thus a grooved decorative sound-absorbing plate is obtained equipped with excellent design.

Abstract: PURPOSE: To make a uniform flock on a surface of an article, by vacuum-shaping a flock transcripting sheet capable of vacuum form to a form similar to the profile of an article, inserting the shaped sheet to the surface of the article, and thermally transcripting the flock to the article.  
     CONSTITUTION: A base sheet 1 capable of vacuum deformation is made of a resin- impregnated paper sheet, nonwaven fabric sheet or plastic sheet. A primer 2 as an adhesive is applied onto one surface of the sheet 1, fibers such as nylon, rayonne, etc. are flocked thereon, and a hot melt-type adhesive 4 such as nylon is applied onto the flocked surface. Thus, a flock transcripting sheet A is prepared. The sheet A is vacuum shaped at a temperature lower than the melting point of the hot melt type adhesive, with a metal die 5 having the same profile as that of an article 6 to be flocked. The shaped sheet A is then inserted into the surface of the article 6 which was deeply drawn. The article 6 may be made of plastics or metal. Thereafter, the sheet A and the article 6 are tightened together by vaccum or compression, and heated to a temperature higher than the melting point of the hot melt type adhesive. After being cooled, the base sheet 1 of the sheet A is split from the article. Consequently, a flocked product is obtained.

Abstract: PURPOSE:To eliminate drastic out-of-focus in the case of shortest photographing or shortest observation and to make the degree of freedom as for the design of an optical instrument large by correcting the output(range-finding value) of a range-finding arithmetic means based on the output of an optical element position detection means. CONSTITUTION:A range-finding block consisting of a flood lens 6, a flooding element 7, a flood lens 5 and a photodetector 8 is set so as to be moved integrally with the moving lens barrel of a photographing optical system 4. Then, a zooming action is executed based on a photographing composition and the optical system 4 is moved. When the composition is decided, a zoom position(distance from an image frame) is read before the photographing by turning off a switch. Besides, a distance to an object is measured by the range-finding block and data is read. Based on the zoom position data and the range-finding data, a correction value is read from a correction data table and the driving quantity of the lens is decided. Therefore, the object is focused without receiving the effect of zoom by extending the lens according to the driving amount of the lens.
